Was reading the interview in my copy of ELLE tonight and looked for it online. She gets asked about thinning hair... Here:

You treat hair loss with Latisse and Rogaine. How does it work?
People who overuse Latisse sometimes see fine little hairs appear on the upper parts of their cheeks, and people have used it on their eyebrows and noticed improvement, so we have evidence it will grow more than just lashes. It’s expensive— up to $140 for 3 ml—so I compound it with minoxidil for diffuse use. For localized hair loss—like when black women have thinning hair around their temples from wearing tight hairstyles—I have patients apply Latisse directly to the area and then put minoxidil on top. We’ve been doing it for about six months, and I have patients who show significant results.
